'The articles in this collection take the reader on a journey from foundational examples and definitions to state-of-the-art theorems and actively researched open problems … Students and those wanting to enter these fields of specialization will want to return to the surveys and expositions for inspiration as they engage with more specialized literature.' Robert Bell, MAA Reviews
